Agreed.
I have a golden rule for this:
if (( management are annoying and like to know about incomplete
registrations
||
you want one point of varifying input so that designers can
shove in as many intermediary pages as possible)
)
&&
You don't have a ridiculous amount of fields to process )
{
place in session
}
else
{
shove in hiddens.
}
I wouldn't start populating your real tables until the registration is
complete since you may end up with lots of incomplete junk in there and
your form design will be governed by any database constraints placed on
your table (foreign keys, and stuff).
Then again, I sometimes have to bend my golden rules. Fortunately Perl
and Gold both bend easily.

I'm not sure how often a user will attempt to complete one form through
multiple browsers. To be honest I'm not sure that he/she should. I think
of a form as one process which may remain persistant due to hiddens or a
session. Once the form has been completed or a user has logged in, the
session data used for the rest of the site should probably be unrelated
and populated separately.

Hi Treveor, I've seen three fixes to this sort of problem in the past, so you might want to see if any of the following apply to your case: 1) Changing Browser - Galeon had me testing for days, when I could clearly see that I was getting the correct header, via telnet to the port. See below. 2) Turning PerlSendHeader Off and sending your own headers. The problem was probably somewhere else, but sending my own headers fixed it. Then again, the problem might not have been elsewhere. 3) Make sure you're not sending your header twice. With PerlSendHeader being on or off, plus a code segment sending a header/or some gibber elsewhere, or even a stray 'print' to STDOUT from some other place, before the header is dispatched. I've had header trouble a couple of time and have often found telneting to the vhost to be a very handy detector of what might be going wrong. If that fails then paracetamol is usually a good cure.

A thought, although I've never been so secure myself and I'm not sure how secure this would be - but it's one of those silly convoluted ideas you have to tell someone. Since you're using mod_perl and apache_dbi, this is just a thought. Use the Crypt::Blowfish_PP to generate an encrypted password and place it as a variable in a package somewhere. During server startup take a password from the command line, some sort of: Paranoid::CryptDBIPassword::promptForPassword getliner. Take the value as my $key and: my $bfish = Crypt::Blowfish_PP->new($key) $Apache::PARANOID::dbiPassword = $bfish->decrypt($encryptedPassword); then whenever you want your password you access $Apache::PARANOID::dbiPassword. Hmm. I think that the guy who wrote Blowfish_PP would cut my danglies off for that one. R.

Help - SEGFAULTS on 'PerlModule' after version upgrade
Ugggh: My software works with the 'original server settings', (apache
1.3.24/mod_perl 1.26) see below(1), under linux.
It doesn't work with 'new server settings', (apache 1.3.26 / mod_perl
1.26) see below(2), under freeBSD.
Symptoms:
With the new build, I get seg faults with 'some' of the PerlModules
included through PerlModule in various virtualhosts. Other modules work.
These packages all run with strict and do not include any XS besides what
may hide under the cover with DBI, Date::Calc and Template. I also have a
headache. The packages were happily being included into my old build and
there is nothing unusual about them. An strace displays the last couple

More Segfaultage - FreeBSD, building apache, ssl, mod_perl fromports
I'm a bit irritated by FreeBSD ports at the moment and need somoene to shine some light. I need to build Apache from ports on a BSD box - it has to be from ports - but i don't want to include mod_perl in as a dso. Thus, I'd like to go to ports and 'Make' with a bunch of options which will compile mod_perl straight into my apache1.3-ssl package. Having run make on www/apache1.3-ssl and www/mod_perl, all I get is segfaults. I simply want to run one make to build it in one go. How???

Apache::Session HELP!
Hi, I'm in major poop.
Got a presentation soon and my just implemented, implementation of

I've set commit to 1 and tied a session to a postgres database. I then
set a field and check the table it's not there.
When I later do a fetch on it, I get a scarey error:
[error] Object does not exist in the data store at
/usr/lib/perl5/site_perl/5.6.1/Apache/Session/Store/Postgres.pm line 81

sub tieSession
{
my $self = shift;
my %session;
my $dsn = "DBI:Pg:dbname=".$DBI_DB.";host=".$DBI_HOST;
print STDERR "\n CREATING SESSION using dsn: $dsn \n";
tie %session, 'Apache::Session::Postgres', undef,

PerlSendHeader and $r->header_out
Hi People With Functioning Brain Cells,
I'm having a brief period of grief, which I'm sure I've been through
before.
I have this situation where I set a cookie using:
$r->header_out('Set-Cookie'=>$cookie);
Now this is all fine, however I'm having a major problem in getting my
header into the right place.
If I call $r->send_http_header right after my $r->header_out(set_stuff)
directive, and then call $r->print("page contents"), I get:
page_contents
HTTP_HEADERS DISPLAYED HERE (INCLUDING COOKIE HEADER)
Now, I experimented with PerlSendHeader being set to On, whilst disabling
the call to $r->send_http_header, yet it then appears to give me a header
which doesn't include the cookie header:
HTTP/1.1 200 OK
Date: Thu, 25 Jul 2002 13:01:12 GMT
Server: Apache/1.3.20 (Linux/SuSE) PHP/4.0.6 mod_perl/1.26
Transfer-Encoding: chunked
Content-Type: text/html
Any idea what is going on?
I'd like to just send_http_header with the headers appearing on top of my
page. It appears to do things in the wrong order. There is no
duplication of headers either.
If anyone can help and would fancy flying me out, I'll even buy you a
beer. :)
My content handler returns the result of another method called within the
same module. This method is passed the request object, which in turn it
uses to send the headers and print the page. This seems 'sensible' to me;
so why is it not working??
Many Thanks,
Fiq

Caching in TT2 or Some Mod Perl oddity
I'm in a baffled state, ladies and gentleman.
I'm using TT2 to ultimately display some pages, however I'm having some
rather odd behaviour creeping in.
In my template constructor I have CACHE_SIZE set to 0.
I have a page which - even after a server restart - reverts to an older
version of the page.
Whilst I was still debugging, I accidently had Data::Dumper doing a print
STDOUT and a lovely $VAR1=[] in the corner of my screen. This has long
since been removed from my code, however I keep going through hits of the
same page - as I said, even after a restart - where either I have the
'correct' funky page, or on the next hit reverting to the old over
funked paged.
>From my understanding of TT2, it's not the actual page which is cached but
some sort of compiled version of the nested code (?). Thus I'm having
trouble seeing how it might be a TT2 problem, especially with
{CACHE_SIZE=>0} whenever Template is instantiated. Is it TT2 or is it
some Mod_Perlus Oddity?
Anyone?
Cheers,

Idiot question: headers at the base of the page.
I'm doing squinty eyed coding and need someone to knock common sense into me. In the right order - as far as I can see - I have my content_type ;send_http_headers; $r->print'ed.

It's probably one of those look at it again in the morning questions. Someone hit me over the head with a hammer please.

I'm working on my own impelmentation at the moment and am planning to have a mechanism in my unoverridden forms controller subclass which hosts methods which can validate data based on types derrived from the form's input names, together with a set of valid fields. For more complex validation I'm planning on subclassing and overloading these methods. The validation routines get called if there is a '_validate' field and these in turn generate an errors structure which gets fed to the View's view of the model. I have a seed method in my controller which determines the execution order, however what it does is call other seeds in the model layer. If all is cool, it does an internal redirect to the next page as supplied in a hidden field - or determined at runtime. You'll have to excuse me for the mubling, but my face is currently being stuffed full of falafal. :) Try some? Fiq.

Thanks. This is pretty much the handler which I'd previously written, with the the exception of s/use/require/.

In my last MVC I just took a look at Apache::Dispatch and I get he impression that if I were to use it then I would have to either PerlModule 'all' my subclasses beforehand, or alternateively use the DispatchRequire option anyway. I'm already using StatINC so I'm going to have to do a toss between code which I've already written and converging to the Apache::Dispatch interface. I'm not so keen on loading all the inheriting classes into memory beforehand, nor setting up multiple handlers for each location.

I could just map from URLs to the specific control subclasses and then use Dispatch to require them - I'd already started on writing a mapping from path names to relative namespaces.

MVC advice..?
Hi, I'm building an MVC architecture site and have hit a design issue. I have varoius Control subclasses which relate to different templates with different behaviour. Now my problem is that I have to assign which Subclass I want to instantiate, based on the script and params. I my last effort I went for a Shared datastructure holding (script, control module pairs) which then allowed one to be dynamically "eval 'use..'"'ed in the main content handler. I found that clunky. I'm building from scratch again and am thinking of just firing up a template and allowing the control to be loaded INTO the view as a template toolkit plugin. What I hate about this is that I'm surrendering my View layer. Is there a neat way of dynamically loading in the appropriate control subclass? Something proven and widely used.

Other than the fact that it gets rendered by mason, it is pretty independent. It's just the fact that in spite of my specifying that it should use inline_perl, it didn't interpolate the inline code which uses custom modules in mason tags.

tt2 using mason tags
Hi, I'm experimenting with conversion of a mason template based system to tt2. I tried to set TT2Tags to mason and then to <% > however this, even with the evaluate option to on, doesn't seem to work. (Apache::Template) I then wrote a custom handler which uses a custom parser, which I've constructed with the tag style set to mason. No go there either. I've got inline perl turned on, however I seem to alternate between a random permissions error (probably a silly oversight) and an unevaluated tempalate. Does this sound familiar? Has anyone had any success with porting straight from Mason? Part two would be to replace the inline code with tt2 directives- thought it was worth mentioning this before getting flamed. :) I'm just after evaluation with mason tags. Anyone?

DBI: selectall_hasref incompatibility
Got a slight problem here.. Does anyone know why there was at some point a major change in the return value for DBI::selectall_hashref? And is there a depricated method which still uses the original prototype? My problem: --- Using DBI V1.19 on my box, the reported prototype is: ""selectall_hashref"" $ary_ref = $dbh->selectall_hashref($statement); $ary_ref = $dbh->selectall_hashref($statement, \%attr); $ary_ref = $dbh->selectall_hashref($statement, \%attr, @bind_values So i wrote shiney happy code and tried it on our production box. On the Production box, using DBI V1.21, the given prototype is: selectall_hashref $hash_ref = $dbh->selectall_hashref($statement, $key_field); $hash_ref = $dbh->selectall_hashref($statement, $key_field, \%attr); $hash_ref = $dbh->selectall_hashref($statement, $key_field, \%attr, @bind_values); hmm.. I sware that I saw something similar about a year ago. I don't want to go about rewriting code, so has anyone found some secret undocumented method which still use the original prototype.

But I use Template Toolkit to generate a dynamic file. How > would the above code work in that situation?! Not how I'd do it, although I'm pretty sure that TT2 has it's own caching mechanism, however in answer to this 'particular question' could you not overload TT's service object to use the preloaded instantiation similar, or more specialised than the one above. (SEE ALSO man Template::Service ..probably) :) fiq btw Apache::Template does let you control caching of templates in memory.
Re: how to pass data in internal redirects?
Surprisingly I'm actually doing a proof of principle on the same theme. I'm developing a set of MVC classes which tie in with either tt2 or mason. I've got abstract Model, View and Controller classes. View can be subclassed into HTML, XML, whatever. I'm using normal classes at the moment, but if I get the go ahead, I'll be replacing these with some sort of pseudo-hash framework. My controller object would use the request object and the environment to determine a framework/templates and which overloaded Controller to generate. There is a generic events handler in the base class, which gets overloaded and which specialises the associated model object for the particular view subclass. I haven't looked at pre-reading the model and passing it into the first content handler, since in my case the model is likely to emerge from a large dataset. Once possible idea, floating in my head is to follow a principle adopted by the first company i was with, in that I could have a transitory daemon through which the data is called - this could possibly cache models requests, preventing second re-reads; also checking to see if the underlying model has changed, as per the original MVC paper. I guess that we can then reaccess the model at any point thereafter so that the the controller doesn't need to reaccess the data. Another point would be to cache the final generated templates, so that the view and controller override interaction with the model, where this data is already persistant. Got my basic framework in place - might make it my first cpan release if I can figure out how - want to share ideas? fiq On Tue, 26 Feb 2002, F.

Re: Mistaken identity problem with cookie (fwd)
Although all your cookies will be probably be going to the same proxy for those requests from the same isp, the tcp-ip session will remain the same and it is most likely that you'll still be connected to the same ip which made the initial proxy connection. My thought is possibly that you're misuing global variables here, or that you have name space issues? Thus the variable which you are setting your cookie value with may not be correctly reset. Just a thought. Fiq

Re: Server error log says "Accept mutex: sysvsem"
Not sure but it just looks like you're getting confirmation of semaphore locking which is probably occuring between the different processes - I'd guess. Then again, it's worrying that it's being directed to STDERR. My guess would be that it's harmless. Check the options with which you rebuilt apache; you haven't got excessive debugging info have you? Someone with much more wisdom may prove me wrong - I'm just filling an empty moment with speculation. :) fiq On Tue, 5 Feb 2002, Al Pacifico wrote: > The following message keeps appearing in my server error log after > building a newer version of Apache (v.1.3.23) and mod_perl (v.1.26) than > I had been running.
